An artillery shell weighing 10 kg flies at the target at a speed of 810 m / s. What is its kinetic energy?

The kinetic energy of a material point Eк, J, moving translationally, can be determined by the formula:

Eк = m * v ^ 2/2,

where m is the mass of the point, kg;

v – point speed, m / s.

Then, for the case under consideration, we have:

Eк = 10 * 810 ^ 2/2 = 3280500 J ≈ 3.28 MJ.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
